Specification of Letters Patent.

Patented Jan. 17, 1922.

Application fll'ed September 10, 1920. Serial No. 409,499.

T aZZwho-m it may concern:

Be it known that I, LEO 'GUDEMAN, a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented certain ceptacle is supported by embracing a portion of the surface of said bulb.

The object of the present invention is to provide a receptacle for the reception of fiuid disinfectant, deodorizer, perfume, or the like, for the purpose of vaporizing the latter by means of the heat radiating from an electrically lighted incandescent bulb, the latter providing a support for the receptacle.

A further objectof this invention is the provision of a receptacle adapted to embrace a portion of the surface of an electric light bulb without substantially diminishing the light emanating from the bulb.

Devices of this general character have been employed in connection with oil lamps, gas burners, and even with electric-bulbs to vaporize a fluid for the purpose of distributing moisture from a receptacle, but the latter has either been supported a distance above the heating medium-or, as in the case of the electric heating medium, the receptacle entirely surrounds the bulb thereby limiting the efficiency of the bulb to a heating medium and practically destroying its use as a light. A device in accordance with 'my lnvention does not substantially diminwith the receptacle;

ish the illuminating properties of the bulb. This feature of the invention is particularly important where the device is to be used in a theatre or assembly for disinfecting purposes, such as required by law in some localities, as the device may be attached to the bulbs without obstructing the light-rays issuing therefrom. A shade or other ornamental means may also be used'in connection in fact the latter may be entirely screened from view and still retain the function of dispensing vaporized fumestherefrom. It will be noted from the following description that the device may be made in different forms so as to be applicable to bulbs held in a vertical position as-well as in an inverted position.

. a vertically disposed bulb.

T be material used in the manufacture of a device of this character may be either metal or glass,'or rial capable of retaining fluid and at the same tlme able to withstand sufficient heat to vaporize the fluid therein e invention consists in the structural features hereinafter fully described with reference to the accompanying drawing wherein Fig. 1 1s a. perspective view of the improved vaporizer.

Fig. 2 is a substantially vertical sectional view through the vaporizer when supported by a bulb in vertical position.

Fig. 3 1s a sectional view of a slightly modified form of the vaporizer supported by Fig. 4 1s a sectional view of still another lf)or11l1)u of vaporlzer supported by an inverted u Fig, 5 is a sectional view of a form of the vaporizer adapted for use in connection with a nitrogen lamp or bulb.

Referring to the drawing,

fluid shown at 11. The receptacle consists of an inner member or wall 12 which is preferably hemispherical in form and provided at it apex with a teat 13. The wall 12 1s designed to conform to the globular portion of an electrically lighted incandescent bulb 14. The lowermost portion of the member 12 has as great a diameter as the greatest diameter of the dome and its lower edge is turned outwardly at substantially right angles to form a concentric flange 15. Secured to the flange 15 adjacent the bend of the latter isthe lowermost edge of a shell 16, having an opening 17 at its upper end through which the fluid may be poured and the vaporized fumes escape.

From the foregoing description it will be observed that the receptacle depends entirely upon the bulb 1A for support and also for heat, the latter acting to vaporize the fluid .11 in the receptacle. inner surface of the member 12 may closely embrace'the surface of the bulb 14, a coating of heat conducting material 18 is provided, the latter also preventing from becoming unseated.

- InFig. 3, the receptacle 10 is formed up out of one piece of material the metal being spun back upon itself and flared in opposite This form prothe receptacle 10 directions at the open end.

Figs. 1 and 2;- 10 denotes a receptacle for thereception of any other suitable mate- In order that the vides a channel 19, for the reception of the fluid 11, and the convergence of the upper and inner portion of the Wall provides a surface adapted to conform in shape to the globular portion of the bulb 14. This form of receptacle is particularly adaptable to lamps wherein it is desired to allow the upper end of the bulb to be exposed.

In Figs. 4 and 5; the construction of the receptacle is of such design that it may be supported upon an inverted bulb, the inner wall 20 of the receptacle 10 of Figure 4 conforming in shape to the tapering side wall of the bulb 14 and the wall 20 of the receptacle 10 of Fig. 5 conforming in shape to the bpdy of the bulb 1-1", thereby permitting the receptacle to snugly embrace the surface of the bulb without interfering with its lighting properties.

In the use of the device either as a disinfectant dispenser, deodorizer, or for evaporating any medical preparation by means of heat for discharging vaporized fumes in a room, the receptacle 10 is placed upon an electrically lighted incandescent bulb or lamp 13 in the manner described. A sufficient quantity of liquid is placed in the receptacle 10 and the electricity turned on, whereupon the glass bulb 14 will be sufficiently heated to heat the inner wall or dome l2 and cause the fluid 11 to vaporize. The fumes from the vaporizing fluid will issue through the opening 17 in the outer member; 16 to the surrounding atmosphere. 1

The device may be used with a table lamp or hanging lamp and when so used I may provide concentrated perfume tablets, soluble in water, placed in the receptacle 10.

I claim 2- A vaporizing device comprising an outer signature.
